The newest era of workforce development at ANS
As most attendees of this year’s ANS Annual Conference left breakfast in the Grand Ballroom of the Chicago Downtown Marriott to sit in on presentations covering everything from career pathways in fusion to recently digitized archival nuclear films, 40 of them made their way to the hotel’s fifth floor to take part in the second offering of Nuclear 101, a newly designed certification course that seeks to give professionals who are in or adjacent to the industry an in-depth understanding of the essentials of nuclear energy and engineering from some of the field’s leading experts.

The capabilities of new methods of fusion alpha-particle diagnostics based on nuclear reactions are discussed. Particularly, the resonant capture reactions between confined fast alpha particles and low-Z artificial impurities in the plasma is examined. In this case, the intensity of the decay gamma rays is proportional to the alpha-particle concentration at resonance energy. Another method is based on Doppler shape analysis of the 4.44-MeV gamma-ray spectra from the 9Be(α, n1γ)12C reaction. Results of an in-beam study of this diagnostic reaction are given. Some questions concerning the gamma spectrometer, a collimator, and a radiation shield are discussed. Estimates of the reaction rates and signal values in the Tokamak Fusion Test Reactor, T-14, Compact Ignition Tokamak (CIT), and International Thermonuclear Experimental Reactor (ITER) are presented. In conclusion, the use of gamma spectroscopy in the diagnostics fusion protons in deuterium-deuterium plasma is examined.
